Kobo forma battery issue, it drains when switched off

k-alex · 02-23-2020, 12:05 PM

I know there are many threads on this forum related to battery issues, but I haven’t come across any concerning the following. I have a Kobo forma and when it is completely switched off my battery still drains around 2% a day; after fully charging it and switching if off it only had 90% battery left activating it after 5 days. 7 days later (12 days in total) and having it switched off and not using it nor switching it on in the meantime it was down to 73%. Is there anybody who has a clue what might be causing the problem? I have my current Kobo for over a year now, the last six months I have been charging it via my laptop. I have WiFi switched off all the time, though I do update the firmware now and then, I currently the latest version. The only thing that I could come up with and might be an potential issue is that I used to charge my kobo the first six months with a regular charger for my old Samsung smart phone, but surely this cannot be the reason for my current battery issue?

If WiFi is on, turn it off.

Worn out or poor quality bettery.
Rechargeable batteries drain slowly all by themselves e.g. sitting on a shelf, not in a device
A typical AA rechargeable as will go flat in a few months, unaided.
Having said that my readers and tablets do not seem to drain at all if powered off for days, so i suspect you have a bad battery. Either that ,or kobo power off does not mean fully office?
